Nrrn STATES JOHN G. MACPHERSON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNORTO THE MAOPHERSON AUTOMOBILE COMPANY, OF NEW JERSEY.

VAPOR'IZER FOR GASOLENE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 655,407, dated August7, 1900.

Application filed November 22, 1899. $erial No- 737,865. (No model.)

T0 to whom it may concern:

Be it known that 1, JOHN G. MAOPHERSON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inVaporizers for Gasolene-Engines, of which the following is aspecification.

My invention relates to improvements in Vaporizers for gasolene-engines;and the main object of my invention is to provide an accurate and acertain means for supplying the necessary amount of the gasolene and forquickly vaporizing the same.

Another object of my invention is the provision of a means for supplyingthe gasolene which is operated and is so adjustable as to only allow thedesired amount of gasolene to be supplied and which is entirely out offwhen the engine is out of operation.

Another object of my invention is the provision of a means for heatingthe gasolene by employing an exhaust-flame at every explosion of theengine, so as to entirely vaporize the gasolene applied thereto.

Another object of my invention is the provision of a vaporizer which canbe attached to any gasolene-engine and which is very simple, durable,and inexpensive in construction and is the embodiment of a very practical and useful mechanism.

To attain the desired objects, the invention consists of a vaporizer forgasolene-engines embodying novel features of construction andcombination of parts substantially as disclosed herein.

In the drawings, Figure 1 represents a side elevation of the inventionwith one end of the cylinders broken away; and Fig. 2 is a verticalsection taken through the cylinders and the casing of thegasolene-supply valve with the operating means connected to asuction-valve, which is simply shown to illustrate the operation of myvaporizer.

Referring to the drawings, A designates the large glass receptacle orcylinder, having located therein the small heating-cylinder 13. Leadingfrom the outside into the heatingcylinder is the flame-conducting pipe0, hav

sleeve or tube G, which is made more secure therein from breakage bymeans of a threaded lug or boss H. Formed in the lower end is a conicalchannel or opening J, which leads upward to the larger straight openingor channel K, which terminates in a smaller straight channel L, whichleads to the gasolene-supply pipe M, which is secured in the enlargedthreaded end N of the tube.

Fitting in the channels of the tube is the rod 0, carrying the needlepoint or valve P upon its lower end, said point being adapted to projectbeyond the lower end of the tube. Surrounding the rod and having one endsecured thereto and the other end abutting against the rim Q'of the tubeis a coiled or spiral spring B to normally hold the needlevalve inengagement in the lower end of the tube.

Pivoted or fulcrumed in the lug S is the bell 7 crank lever T, whoseinner end S is adapted to be below the needle-valve and is provided withan inclined guard or plate T to cause the gasolene to run off of thelever and drop upon the small cylinder. Attached to the outer or lowerend U of the lever is a rod V, which is connected to a gas-inlet orsuction-valve W, said valve being adapted to pull upon the lever, whoseinner end moves upward, contacting the lower end of the needle valve andopening the tube, thus causing the gasolene to flow therefrom and downupon the heating-cylinder, where it is vaporized and passes out of thegas-supply pipe X to the engine. Thus it will be observed that when theengine is thrown out of operation the supply of gasolene is stopped, andthereby all danger is avoided.

It isevident that I provide a vaporizer which is very simple in itsconstruction and by reason of its few, parts is noteasy to put out ofoperation by breakage, which is provided with a supply-valve that ismade adjustable by simply turning a milled ring or Passing through 50cylinder and having a free end within and 7 one without the cylinder,aguard or plate carried by the lever near the free inner end thereof toprevent gasolene from flowing too far uponthe lever, and means foroperating the lever to cause its inner end to contact the valve to admitgasolene to be vaporized. In testimony whereof I aftix'my signature finpresence of two witnesses.
